Mentioned in an earlier article an issue with progressing through MyCareer mode, specifically on the Xbox 360 and seemingly isolated to the 4GB hard drive version of the console, was immediately identified in NBA 2K13. Those playing the mode have found it impossible to advance beyond the first game in the regular season as the game freezes up at that point.
2K Sports yesterday submitted a patch to Microsoft to address the issue. It is expected to be expedited through the certification approval process as both companies certainly have the motivation to get it out as soon as possible. Potentially then it could release sooner than the typical evaluation period for most updates which can take up to 2 weeks.
